Assertion : Actinoids show larger number of oxidation states than lanthanoids.
Reason : Highest oxidation state shown by lanthanoids is +4 while that of actinoids is +7.

A

Statement 1 is True, statement 2 is True, Statement 2 is Correct explanation for Statement 1.

B

Statement 1 is 'True, Statement 2 is True, Statcmcnt2 is NOT a correct explanation for Statement I.

C

Statement 1 is True, Statement 2 is False.

D

Text Solution

Verified by Experts

The correct Answer is:
B
In lanthanoids, energy gap between 4f and 5d subshells is large while in case of actinoids, energy gap between 5f, 6 and 7s subshell is very small.
